SPRING FOR CARRIAGES AND RAILROAD-CARSJ Specification of Letters Patent No. 26,668, dated January 3, I860.

To all whom it may concern: I

Be it known that I, HEMAN GARDINER,Of the city of New York, have invented a new and useful Improvement in Springs Suitable Either for Carriages or Railroad-Cars, and that the following is a full and exact description thereof, reference being had to the drawings accompanying and makingpart of this specification. r

The nature of my invention does not consist in the using or applying merely ofthe coiled or scroll steel spring, so as to close the coil when under pressure. I make no claim whatever to the use of such a spring independently of other arrangements; but the nature of my invention consists in arranging and combining such a spring upon a cylinder with semi-elliptical springs placed in recesses on the periphery of such cylinder as is hereinafter particularly set forth.

In the drawings accompanying, Figure I, is a side elevation of a spring, the box in which it rests, and the pedestal or bracket by which the spring is connected with the carriage body above it. Fig. II is a side elevation of the coiled blade, the cylinder and fixed bearing or axis at the center. Fig. III, is an end elevation. Fig.IV, shows the semielliptical springs in recesses upon the surface of the cylinders, and underneath the coil.

Fig. V, is. a bracket or pedestal of one arm, suitable for carnage springs.

In all the figures like letters represent like parts.

. In Fig. II, A, represents the coiled or scroll spring; B, is a cast iron cylinder uponwhich the spring is fastened; G, the axis or central bearing upon which the cylinder lic box D, as shownin Fig. I, in the sides of.

' rests. The fixed end ofjthe blade 40 1 which are squareopenings to receive the axis, asseen at b, b.

The cylinder B, is not acornpletecylinder or circle, but is depressed or zparedaway y from the point a,-:so as togive agradual bearing to the blade. Upon the surface. orj periphery of the cylinder are placed, on opposite sides of the cylinder, semi-elliptical r r springs, H, H, which are placed in recesses;

in the surface of the cylinder I (their ends; be.-

ing free) wherepthey are held; the coiled blade being over these springs, combinesjits. action with that of the smaller springs The cylinders should be cast hollow, [for W1 lightness. The outer sides of the Qscrollfioi: coiled blade, are curved upwardlsoasjto re I ceive a suitable bracket or pedestal to; i support the carriage! And these springlsi; may be usedsingly or inipairs, with yjsingley or double bracketg 1 Having thus described my improvement; I what I claim therein as my invention is Combining and". arranging the coiled; springor blade A, with the looselaux iliary semi-elliptical springs H, 1H, uponh and around the central. cylinder, having uponits periphery the recesses to receive the. loose; springs; the wholeoperating together in the manner and for the purposes described.
